Plastic tube sleeves are caps made from plastic, which is a type of plasticizable synthetic polymer material. It, along with synthetic rubber and synthetic fibers, forms the three essential synthetic materials in today's daily life. Specifically, plastics are mainly composed of synthetic resins and can be shaped under conditions of temperature and pressure. Plastic tube sleeves maintain their shape at room temperature. The main performance characteristics of plastics, compared to other materials, include the following aspects.

Lightweight plastic is a material that is relatively light, with a relative density ranging between 0.90-2.2.

2. Poor thermal conductors, such as plastics, which are generally 1/75 to 1/225 as conductive as steel, offer noise reduction and vibration damping. The microscopic pores in foam plastics contain gas, providing excellent insulation, soundproofing, and shock resistance.

3. Excellent chemical stability: The majority of plastics have good resistance to corrosion from acids, bases, and other chemicals.
